print formatting

[vsoler]

Hello,

My script contains a print statement:

print '%40s %15d' % (k, m)

However,

1- the string is right adjusted, and I would like it left
adjusted
2- the number is a decimal number, and I would like it with
the thousands separator and 2 decimals

If possible, the thousands separator and the decimal separator should
use my local settings.

Is there any way to achieve this?

Left-alignment is achieved by using a negative width.

You can use the locale module to generate thousands-separated numeric
string representations:

>>> from locale import *
>>> setlocale(LC_ALL, '') # locale is otherwise 'C'
'en_US.UTF-8'
>>> locale.format("%12.3f", 123456.789, grouping=False)
' 123456.789'
>>> locale.format("%12.3f", 123456.789, grouping=True)
' 123,456.789'

regards
Steve

Traditional:
>>> print '%-40s|%15s' % (k, locale.format("%d", m, grouping=True))
hello | 1.234.567

New:
>>> "{0:<40} {1:15n}".format(k, m)
'hello 1.234.567'
